Greater Rift 100 has been beaten.

This is kind of embarrasing. Korean team of 3 reached grift 100 with only using Rimeheart/Furnace/EP. Same team/clan has completed 4 players grift level 94 in 9min 14sec. So Rimeheart/Furnace/EP is quite balanced indeed!

I will echo the sentiments of others - this is why we have PTRs. A huge thank you to everybody who has been helping us test rifts thus far. Our internal testing team identified a number of skills and items to keep an eye on and Exploding Palm, Rimeheart and the Furnace were all on the list. The dedicated players on the PTR have shown what is possible when the game is stretched to the limits.

We're looking to make changes to Exploding Palm in the next PTR patch. Of the three (Exploding Palm, Rimeheart and the Furnace) we feel this is the biggest offender. It's not clear if Rimeheart is as offensive if you're not able to further transfer the resulting damage onto elite monsters via Exploding Palm.
